Periwinkle

Uses & contexts

Nearest named colours, and how they differ

• Lavender is the closest, at ΔE00 10.7 from periwinkle: 8 points lighter, 17 points less saturated and 1° round towards blue. That is clearly different, though many people would use one name for both.

• Mauve is next, at ΔE00 11.4 from periwinkle: 5 points darker, 18 points more saturated and 22° round towards red. That is clearly different, though many people would use one name for both.

• Thistle is next, at ΔE00 11.7 from periwinkle: 3 points darker, 11 points less saturated and 33° round towards red. That is clearly different, though many people would use one name for both.

• Lilac is next, at ΔE00 15.0 from periwinkle: 12 points darker, 2 points less saturated and 33° round towards red. That is a different colour at a glance.

Distances are CIEDE2000 between catalogue reference values; lightness and saturation are CIELAB L* and C*. How to read a ΔE figure · Measure any two colours

Using periwinkle in a real space

Worked out from this colour’s own measurements — its lightness, saturation and undertone — rather than written for it. That is why the guidance differs from one colour to the next even when the two look similar.

What role it can play

This works across a range of sizes. At chroma 27 it is assertive enough to register on a small object and restrained enough not to dominate a wall.

• Walls and large surfaces

  strong

  Chroma 27 sits inside the range walls and large surfaces carry without taking over the room.

• Secondary surfaces

  strong

  Chroma 27 sits inside the range secondary surfaces carry without taking over the room.

• Furniture

  strong

  Chroma 27 sits inside the range furniture carry without taking over the room.

• Rugs, curtains and bedding

  strong

  Chroma 27 sits inside the range rugs, curtains and bedding carry without taking over the room.

• Trim and joinery

  strong

  Chroma 27 sits inside the range trim and joinery carry without taking over the room.

• Accents and small objects

  strong

  Chroma 27 is exactly what an accent is for. The saturation that makes this difficult across a wall is the reason it works on a cushion, a door or a single chair.

How it behaves under different lightmoderate

Under warm bulbs

Warm bulbs emit little short-wavelength energy, so there is less for a blue to reflect. There is enough chroma here to survive it, though it will read warmer and slightly duller.

Under cool bulbs

Cool light flatters this — it will hold its identity and may read slightly more saturated than in warm light.

In daylight

In strong daylight a colour this light approaches the top of its range, and differences between it and other pale colours compress. It can look washed out at midday in a south-facing room and return in the evening.

In a dim room

Enough lightness and chroma to stay recognisable in a dim room, though it will lose some saturation.

Compared with the sample card

Pale colours almost always read darker in place than on a card, because a card is seen against white and a wall is seen against itself. Expect a step down.

What colour temperature actually means · Why two bulbs at the same rating can differ

With wood

• Oak · Walnut · Pine · Plywood · Light wood (ash, birch, beech) · Dark wood · Reddish wood (mahogany, cherry, teak)

  works well

  Opposite in undertone to Oak, Walnut, Pine, Plywood, Light wood (ash, birch, beech), Dark wood and Reddish wood (mahogany, cherry, teak), but 2–61 points apart in lightness or far enough round the hue circle that the difference reads as deliberate contrast rather than as a clash.

The amount of timber matters as much as the tone: one piece is an accent, a floor plus joinery is the room’s dominant colour. More on working with wood tones

With metal fittings

• Black metal

  works well

  Shares the cool bias of Black metal, so they agree about the temperature of the room, and 76 points of lightness keep it readable as separate from this colour.

• Brass · Gold-tone · Copper

  works well

  Shares the cool bias of Brass, Gold-tone and Copper and sits within 16 points of them in lightness, so expect a quiet, tonal relationship rather than a contrast.

• Chrome · Stainless steel

  needs care

  Sits close to Chrome and Stainless steel without matching them (ΔE00 17–18) — near enough that the eye reads an attempted match and far enough that it fails. Either move decisively away or repeat the tone exactly.

Metal carries more attention than its area suggests, so repetition matters more than the exact finish. More on metals and mixing them

Where it can go wrong

• No characteristic failure mode stands out from this colour's measurements — it sits in a comfortable range for lightness and chroma alike. The usual caution still applies: judge it from a large sample, in place, in the light the room actually gets.

Lighter, darker & directional variants

Calculated directional adjustments. Some directions converge on the same result from this starting colour — shown as one merged card with an explanation, not repeated duplicates. Generated shades link to a curated profile only when one is close enough.
